1) The main Aim of the AI system is to provide a solution for real-life problems by acting and thinking humanly. Whenever an agent is confronted by a problem, what is the first step that it follows towards searching a solution to the problem?
  1. Searching for relevant data in the surroundings
  2. Searching into its own knowledge base for solutions
  3. Seeking for human inputs for approaching towards the solution
  4. None of the above

2) Which of the following mentioned searches are heuristic searches?
  1. Random Search
  2. Depth First Search
  3. Breadth First Search
  4. Best First Search


  1. Only iv.
  2. All i., ii., iii. and iv.
  3. ii. and iv.
  4. None of the above

3) Which of the mentioned properties of heuristic search differentiates it from other searches?
  1. It provides solution in a reasonable time frame
  2. It provides the reasonably accurate direction to a goal
  3. It considers both actual costs that it took to reach the current state and approximate cost it would take to reach the goal from the current state
  4. All of the above

4) Consider the following statement:
"The search first begins from the root node and the first one of the child node’s sub-tree is completely traversed. That is, first all the one-sided nodes are checked, and then the other sided nodes are checked."
Which search algorithm is described in the above definition?
  1. The Breadth First Search (BFS)
  2. The Depth First Search (DFS)
  3. The A* search
  4. None of the above

5) Consider the following statement:
"In AI search algorithms, we look for a solution which provides us the most optimized way in terms of both time and cost to reach from the current state to the Goal State."
State whether the above condition is true or false?
  1. True
  2. False
